These surveys of the type Behavior, Attitude, Practice have been carried out in the Ecole Française where the same questionnaire has been distributed among the primary school children to complete by their parents. Only the data pertaining to Europeans, Lebanese, and North-Americans are presented. The proportion of French expatriates is 80%. A progressive decrease is noticed in the regular taking of chemoprophylaxis: the percentage varies between 86 and 43% according ot the duration of residence in 1989, to between 57 and 16% in 1992. Chloroquine alone remains the most widely used product, especially in long term expatriates. The association chloroquine-proguanil is mentioned only by a quarter or respondents. Apparently efficient, it is especially taken by people exposed for less than 4 years. Amodiaquine, although contra-indicated for prevention purposes, is cited in 1992 by 9% of subjects taking regular chemoprophylaxis; other products are only exceptionally used. In curative treatment, which generally is presumptive, halofantrine is since 1990 the most widely used drug, especially in children. In contrast, a relative disclaimer is noted for the amino-4-quinolines, due to resistance, but also and with no justification, for the association sulfadoxine-pyrimethamine and, to a lesser degree, for quinine. The occurrence of attacks considered to be malarial and their frequency, remained stable during the period of study.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":7901,"journal":{"name":"Annales de la Societe belge de medecine tropicale","volume":"73 2","pages":"91-9"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19353853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These data raise some questions and hypotheses on the nature and the dynamics of the epidemiological factors involved. The geographical distribution of the infection in the global population is heterogeneous. Ever since the first surveys, the virus is widely spread at low level, in the rural as well as in the urban areas, covering a large territory, from Chad to Gabon; later it tends to focus on the large metropolitan and secondary towns. The endemicity is more pronounced in a double urban conglomerate (Kinshasa, Brazzaville) and in two regional foci, the southwest of the Congo and the south of Shaba; in the two towns the prevalence rate does not progress between 1985-86 and 1991-92. The Central African Republic has suffered an active epidemic outbreak, affecting the capital and the whole network of secondary towns. The epidemiological discontinuities noticeable across Central Africa, may represent different stages of the same process or be connected to the stake of different eco-epidemiological systems.</p>","PeriodicalId":7901,"journal":{"name":"Annales de la Societe belge de medecine tropicale","volume":"73 2","pages":"127-42"},"PeriodicalIF":0.0,"publicationDate":"1993-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19353848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A case control study was conducted between October 1990 and March 1991 to better document this phenomenon. The majority of confirmed cases presented in persons who had recently sojourned in an endemic area (relative risk = 18). All except one of the other patients were carriers of plasmodium species that can cause late recurrences, which is compatible with the absence of local transmission. The presumptive diagnosis of malaria, as it is routinely made in the health centres, is not very specific (60%) and it has a positive predictive value of only 10%. This implies that an anti-malaria treatment is useless for 90% of the patients who receive it. It also means that the true malaria incidence rate in Kayanza can be estimated at less than 1 per thousand per year. We propose an alternative diagnostic strategy based on the risk differences between population sub-groups.

The black fly larvae live in fast running water courses. Thus, it is difficult to insure a prolonged exposure time in natural conditions.
